A digital cart is an online tool that allows users to collect and manage items they wish to purchase from an e-commerce website. It functions similarly to a physical shopping cart, enabling customers to browse products, add them to their cart, and review their selections before completing the purchase. Digital carts often include features like quantity adjustments, price calculations, and the ability to save items for later. They are essential for online shopping experiences, making it easier for users to organize their purchases and streamline the checkout process on platforms like Amazon or eBay.
